n pair ofy arcuate angle irons 32 are arranged at the upper end of the open end 29 fora purpose to be described.v The upper end ofv the ramp is secured to the platform y,16 by braces 33 and 34, and the ramp is also suitably supported by thebraces 26y by depending braces 35. Horizontal braces 36 also areysecured vto thelupper. end of the foundation 26 and to the ramp as Vshown in Figure 1. TheJ side walls of the ramp are provided near their lower ends with a pluralityof openings 37 for a pur ose tobedescribed.

Re erring to Figures 1,2 and 6, the numeral V38 designates an apron including suitably f braced sidewalls 3,9 and a bottom 40. A dei a barge42.- "The stop 41 is adapted to prop-,-

The upper end of the apron is provided with an extension-43 atk Leach side, `and a bolt 44 passes through Vearch extension and one ofthe openings 37; whereby ,i vit will be apparent that the apron is pivotally Ymes `connected ytothe ramp.` vThe bolts 44may be be provided;'forfelevating the lowerend' of f the apron when a barge is to be'movedoutf ofy y operative'position and a' loaded barge brought g into position.- As shown in Figures 1 and 3,

'suitable siqiports 45 arey arranged on posts 46 ,and are provided with chain blocks 47'.'y These f' 1 blocks are' provided ywith the usual chains 48 secured atene endftothe lower portion ofthe apron whereby'movement of the chain vis to be brought into-the position indicated 'in rFigureljwithone end thereof arranged .be-

neath the lower end of the apron. I The opposite endY of `thebarge may-be provided with ar pair of upstanding posts 49 connectedby a transverse beam 50. As shown in Figure? I prefer to employan I-beam 50 having a series of openings 51" in "onebasethereofto` selectively receive al bolt 51-carried by a sheave 52. A Lnut53 is arranged on the endof the bolt 50. The construction "just described is provided to permit kthe sheave'52tobe adjusted ink differentpositions with respect tothe vWidth/ofthe barge and it will be apparent that'any suitable'form-of adjusting means fmay be employed, Atf its forward end, the

barge 42 is provided with aninclined slidek 54 suitably supported by braces 55. The up.

ydrawin s. rFhis bucket includes sides 57 and a solid ottom 58. yThe forward end of the bucket is open as shown at 59 and is closed at its rear end as at 60. A transverse brace 6l issecured across the top of the forward end ofthe bucket, and a vertical connectingfmem- 'ber .62 extends from the brace 61 to the bottom ofthe bucket and is provided with a series of openings 63. A pair of connecting links 64 are pivotally connected to the mem- -ber62 by a-bolt 65 which passes through one offthe kopenings 63. The forward ends of the links 64 `are connected b v a bolt 66fto an eye 67 secured to the end of the cable 21. The rear lwall= of the bucket is provided with an upstanding brace 68 in which is supported a sheave 69, and the cable 22 passes under 'thisf'sheavei Any auxiliary sheavey 70 is adapted tomaintaiu the cable 22 in proper V'position in the sheave69. The end of the cable 22 is secured to the rear end of the bucket asjat 71. W y

f7 Betweenthesheave19 and the eye 67, the fcable 21 ,passes over a sheave 72 supported upon the forward end of they platform 16. The'ea'ble" 22 passes around a sheave 73, also supported'upon the 4platform 16, and from thisqshe'ave -the cable 22 passes under the sheave 69, thence over the sheave 52,l the end fof'the cable 22 being secured to the bucket y56 at 71, asfpreviously stated;

f* In Figures 10 and 11 of the drawings I have shown a somewhat modified' form of construction particularly adapted for transferring Vmaterialffroln a barge to trucks, tram cars, or to anothervessel.y .ln the modified form 'of the'invention thebarge 42 is provided with the `same Voperating elements previously described, and these elements need not be referred to'again in detail. As shown, the ramp is eliminated, yand an apron 74 is employed. Thisaprony is pivotallywconneeted as at 'T5 to a supporting structure 76. The apron is similarin construction at its lower end to the apron 38 previously described, while the upper end-of the apron 74is provided with means foritilting the bucket to dumping position as indicated at vthe upper end of the ramp 27. This means includes the depending angle 4irons 7 6', correspondingto the angle irons 30,

I claim:

' 1. A conveyor trough comprising a substantially U-shaped inclined body having an opening adjacent its upper end, a depending support carried bysaid trough within the ylower portion of said opening and adapted to support aconveyor bucket therein, and a y f pair of angularineinbers arranged at the upper limit of said opening and having their lower endscurved inwardly toward said sup- 2. A conveyor' trough comprising an ins s v clined body7 a depending support arranged at m the upper end of said body and adapted to support a conveyor bucket, and a member arranged aft the upper end of said body and y curving inwardly toward said support whereby the lower end of said body is spaced from fr, thelowerr end of said support a'distance less than the-height ofthe conveyor bucket.

3. In combination, an open topped cargo carrier, a cargo receiving structure mounted wholly independent of said carrier, a trough arranged between said carrier and said structure, a scraping element movable between said carrier andr said structure, and means for operating said scraping element whereby n it will be in constant engagement with said ,5 trough during' its travel throughout the length ofthe trough, said` trough comprising a lower inclinedapron and an upper inclined ramp, the yadjacent ends of said apron and r said ramp being` pivotally connected to each `l other7 the upper end of said ran'ip being provided with a depending' discharge opening.

In testimony whereof I nay signature.
